"This invention relates, in general, to. :hlank stock tusediby wall paper hangers and wall decorators for the purpose .ofzproviding a smooth even -Sl1 1lffiCQTli0 support wallrpaper or other mail :decorating mediums, and the invention particularly relates to blank stock constructed ifromxmaterial, pie vcomparatively heavy-weight and .consistency, LW'hiflh'ziS eadapteddorprov-iding a smoothrandeven background when properly :applied .to a wall, so

My invention 1 consists :in providing blank stock wh'osetlongitudinal edges form sinuous lines of a M5 definiteand precise formation. "Each longitudinal edgerconsists oiaseries oi uniformiscallops which sheets .of :blank stookcto .be placed upon a wall so that their longitudinal edges mesh and ibecomegegisterably aligned with respect to each 12D ether to ormla :multiecurved seam therebetween.

"It :is a wellaknoumsfact thatiall plastered suriaoes contain minute pores that are not satisv iaotorily :ClOSBd why -a surface paint. Also shrinking and expanding :forces in the plaster, or the i;imbers.,caused by variance in temp ratures or vibrations created by various means, cause cracks .135 in :the plastered surfaces. It is obvious that when suchlconditions exist, the hanging of any fabric or wall paper on such a suriacemay a esult in its distortion, cracking-or tearing. By the use of a blanking stock constructed in accordance with l 49 my invention, the inherent tensile strength of said stock tends to counteract, stabilize and distribute over a greater area of the supporting wall any unusual strains and stresses caused by the cracking forces. This permits the laying of the finishing sheets over walls having relatively large cracks and lines therein than has heretofore been possible, without the cracks and lines becoming a disfiguration to the outer finishing sheet of material, that is to form the finished sheet.

,5 It has heretofore been impossible to utilize relatively heavy long-fibered blank stock having parallel longitudinal edges because these edges, after the blank stock was applied to a wall, had a tendency to curl up in drying, since the shrinkage .m caused by the drying of the paste could not be dis- .sipated,-:arrested, controlled .or .cdirected, Furthermore, the parallel longitudinal edges oftentimes permit a crackinthe lwal1',.star.ting either at :orrnear the meeting edges, joint or seam, to ifollow this weak line, resulting .in damage to the deo0- 59 rating medium. Also, the decorating medium is usually manufactured with parallel longitudinal edges, and these ledges :may sometimes fall :at or near athe meeting edgesof :the blankzstock. IT'hiS is .not desirable at any itime, :but,'=;by the use .Of 6.5 my invention, :t'heishrinkage ior expanding forces are controlled .andldirected in such a manner that the edges ecannot curlpit islimpossible for the :par allel edges of the decorating medium to :meet :the edges of the blank stock, and no-fissuracamfollow down the multi-curmed joint. :By this construction 113116 shrinking "forces are directed toward the base :of the tongues where the same are arrested and spent.

Where blank stock :is hung of the type here 7,5 outlined and disclosed there ban-"beam possibility of a double melt occurring in the blank stock that shows through the outer finishing sheet and it will produce a much smoother {10b and one that will remain intact and in fine positionrwith i'f-reedomrfromilooseness and :fromedeepeel, and :free- :dom irom wall cracks showing, that were in the Wall before the blank stock and the outer sheet were laid. r

:Qne ro'fthe objects rof :theinvention is to provide a wall covering made of paperrmaterial which tongues formed with .indentures therebetween, ea ohtongue :having an ;.area ,across the low- ;er zportion thereof which the inwardly di- :rected iorceslof shrinka e are permitted to spend 99 themselues without disturbing the outer properly located and pf the tongue with respect to its tongue on the blank shceteomple- .,y-,o, it. v ,c

A still further object of my invention consists in providing a background upon which relatively thin veneer may be hung for providing a room having the semblanceand appearance of being made and sealed with a Wood surface.

An object of the present invention is to provide 190 animproved blank stock in which the edges are so shaped that the sheets mutually support and complement each other at the regions where they meet in creating a smooth and even supporting surface which practically eliminates the risk of distortion or cracking of the wallpaper or other decorative medium, and, at the same time, an approximately air-tight intimate contact is formed between the blank stock and wallpaper or veneer.

A still further object of the present invention is to provide a blanking stock of strong and durable construction which may be readily applied and which will afford, when applied, a smooth, even surface upon which any decorative medium, such as wall paper, linoleum, paneled wood or veneer may be effectively and quickly applied.

Another object of my invention is to provide a blank stock which is adapted to arrest and control the shrinkage and expanding forces inherent in a plastered surface and to prevent fissures from spreading excessively, to arrest and control the movement of the blank stock itself and to prevent the edges of the decorating medium from falling adjacent the seam or edges of the blank stock.

The particular object of my invention is to overcome not only the disadvantages of the present type of blank stock and present type of cloth sheeting but also those disadvantages which have become apparent in the application of blank stock heretofore invented and to provide a blank stock made of heavy paper that is inexpensive, simple and durable in construction and that can be quickly and easily manufactured and installed without detriment or change to the decorative medium.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and in preferred form of embodiment of which is hereinafter shown with reference to the drawing which accompanies and forms a part of this specification.

In the drawing:

Fig. 1 is a perspective, end View of a room upon which blank stock of my new and improved design has been placed to illustrate the finishing sheet as having been placed over the blank stock with some of the outer coating broken away to show my sheet in use.

Fig. 2 is a plan View of a portion of the blank stock illustrating the sinuous edges that are disposed at the longitudinal edges of each edge of the blank stock.

Fig. 3 is a fragmentary, plan view of the abutting sheets of blank stock and illustrating the abutting edges in place that form the meeting or abutting edges of the blank stock.

Like reference characters refer to like parts throughout the several views.

I provide a sinuous line 1, upon the oppositely disposed longitudinal edges 2 and 3 of a sheet, or roll of blank paper or other material 4 forming thereby uniform scallops. The edges 5 and 6 meet to form tongues, as shown at 8 and 9, and the base of each tongue has the same contour as the apex of said tongues, as shown at 10 and 11; that is, the apex and the base of each tongue are formed from identical segments of a circle. By this construction it will be seen that the tongues formed in the blank sheets or rolls are adapted to mesh with tongues of corresponding sheets, thereby forming a sinuous edge. The purpose of forming such an edge has been specifically set forth hereinbefore. This construction also produces a blank stock which will, when placed on a supporting surface, remain in a relatively fixed relation thereto and whatever expansion or contraction may result from the application of a binding medium such as paste, on each side of the blank stock will be directed toward the tongues and be dissipated or spent at the base of each of said tongues, thus preventing the possibility of injuring or distorting, in any way, the decorative medium 12.

While the embodiment herein shown and described is admirably adapted to fulfill the objects stated, it is to be understood that it is not intended'to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.

What I claim is:

1. Wall covering for the purposes described comprising a sheet of material having its opposite edges formed with tongues equally spaced apart in the direction of the length of said sheet, the tips of each tongue being formed on a radius and the sides of said tongues extending tangentially from said tip in angular relation to the longitudinal centerline of each of said tongues, and said sheet adapted to be placed alongside of other sheets of identical formation with the abutting tongues of all of said sheets in intermeshing relation with each other.

2. Wall covering for the purposes described comprising a sheet of paper formed along its edges with a plurality of integral tongues equally spaced apart throughout the length of the sheet, the tip of each tongue being formed on a radius and the sides of the tongue extending tangentially from the tip in angular relation to the longitudinal centerline of the tongue.

3. Wall covering for the purposes described comprising a sheet of paper formed along its edges with a plurality of integral tongues equally spaced apart throughout the length of the sheet, the tip of each tongue being formed on a radius and the sides of the tongue extending tangentially from the tip in angular relation to the longitudinal centerline of the tongue, and the corresponding sides of two adjoining tongues converging tangentially into a radius equal to the radius of the tip of the tongue.
